LAMP.

Specification of Letters Patent No. 31,983, dated April 9, 1861.

To all whom it may concern:

Be it known that I, Anson J UDsoN, of the city of Brooklyn and State ofNew York,

have invented a new and useful Improvement in Lamps for BurningKerosene, Coal, or SimilarOils; and I do hereby declare that thefollowing is a full and exact'description of the same, reference beinghad to the accompanying drawings, with letters of reference markedthereon.

The nature of my invention consists in constructing the cone A of glassor other transparent material by which the whole flame is madeserviceable, thereby causing an equal illumination with a lessconsumption of oil. The cone A necessarily rises from one half to fiveeighths of an inch above the base of the frame and if opaque must causethe loss of a considerable proportion of the light generated.

The construction is the same as the opaque metallic cones now in use,and will be readily understood byreferring to the accompanying drawing.7

Figure l is a longitudinal elevation of a cone of my inventionconstructed of glass or other transparent material. Fig. 13 is a plan ofthe same. Fig. 2 is a general View of a lamp as arranged with a cone Aand Wick tube B for burning kerosene or coal or similar oils. "I,

Having thusQI believe fully described my invention, I now set forth myclaim. I do not claim any particular form of cone but What I do claim asmy invention and desire to secure by Letters Patent is The constructionof the cone A, or its equivalent of glass or other transparent materialas and for the purpose herein described.
